Yes, and you are talking about foreign students studying in the U.S., which is rather different from regular immigrants. For men to outnumber women in immigration, and especially initial immigration, is not unusual.
ME immigrants in the US tend to be highly educated, with an emphasis on education extended to their women as well.
“Figure 2 shows that in contrast to immigrants in general, those from the Middle East tend to be more educated than natives. While a very large share of immigrants overall are high school dropouts, those from the Middle East are only slightly more likely to be dropouts than natives. At the higher end of the education distribution, almost 49 percent of Middle Eastern immigrants have at least a bachelor’s degree compared to only 28 percent of natives; and at the highest end, 21 percent have a graduate or professional degree, more than twice the percentage of natives. Overall, the figure shows that immigrants from the Middle East are better educated than other immigrants and natives.”

When twenty+ guys are telling you they only have two ME women for their dinner/gala, it is way beyond “initial immigration”; outside of the few Christian girls from Lebanon and Syria, there were none from the ME.
